RaspiBolt VS electrum-personal-server

I would start my research with Umbrel, Raspiblitz, Mynodebtc, RaspiBolt or Embassy. A couple of guides: https://thecryptogarage.com/umbrel-linux-ubuntu-node-build/ https://stadicus.github.io/RaspiBolt/

If you're willing to DIY a bit, I strongly recommend the RaspiBolt guide!

RPi4 in a box. Used the RaspiBolt guide for initial software setup.

Sounds like you'll enjoy the Raspibolt guide - it's how I set up my node. GUI stuff is in the "bonus" section. r/raspibolt for help

If you're the DIY type I strongly recommend the raspibolt tutorial - geared for a Pi but good for any device, just substitute arm64 for your architecture.

Check out the raspibolt tutorial. Geared for a Pi but applies well to any capable device

Another way is to setup a full node on a dedicated device and follow the guide to setup everything so you can connect a hardware wallet to your node: https://stadicus.github.io/RaspiBolt/

Follow the instructions on Electrum Personal Server. Don't let the word "server" deter you. Often this can mean "open a localhost http port". Assuming you have enough privledge on your PC to bind a TCP/IP port, you should be fine.

There are some server implementations that make use of XPUBs. For instance, Electrum Private Server is an implementation that must be configured with XPUBs of all wallets you want to use with it, so it can scan the blockchain for them, in return for much lower resource usage than regular servers that have to index the necessary information of every transaction ever made. But EPS is only suitable for private use, hence the name.

(A) Link it to your own Bitcoin Core node. You will need a little indexer called Electrum Private Server. https://github.com/chris-belcher/electrum-personal-server/releases . Once you do that, you won't have to ask any other Bitcoin node for transaction history or to broadcast your transactions. You become your own bank, literally.

Electrum Personal server v0.2.4 (Released: 16th June 2022) - https://github.com/chris-belcher/electrum-personal-server/releases

You need Electrum PERSONAL Server, not Electrum Server. Big difference!

To gain some privacy by using Electrum you should set up Tor on Network preferences or by installing your own Electrum server via Electrum Personal Server, ElectrumX or Electrs.
